Definitions

  • the difficulty with multi-stage filters is to accommodate sufficient filter surface in the space available.
  • a larger filter surface is often required for particle filtration than for odor filtration or gas adsorption.
  • the object of the present invention is to create a filter element in which the size of the filter surfaces is optimized for a specific filtration task with a given installation space.
  • a further object is to create a filter element in which the filter area available for particle filtration is larger than the filter area available for odor filtration or gas adsorption.
  • the first bellows and the at least one further bellows of the filter element described above can be formed from different filter media. In this way, the filtration performance of the filter element can advantageously be adapted particularly well to the requirements and matched to the intended use of the filter element.
  • the filter medium of at least one bellows can have a particle filtration layer made of nonwoven fabric.
